Cargo Securing - Comparison of Different Quality Roads

Abstract

The article deals with the subject of the impact which road surfaces have onto cargo and the securing of cargo against shocks during road transport. The applicability of the key EN 12191‑1:2010 standard is discussed, not only for common conditions, but also for specific transport conditions on low‑quality road surfaces. Part of the article involves carrying out a transport experiment on a road paved with granite blocks and on a highway, from which data on the impact of shocks on cargo (acceleration coefficients values) were obtained. The data were statistically evaluated and compared to the normatively determined values of these acceleration coefficients. A parametric statistical analysis (two‑sample t‑test) was used to compare the values of the acceleration coefficients from the two types of surfaces. The analysis conducted shows statistically significant differences between the data measured on the road paved with granite blocks and on the highway. Using correlation analysis, the dependence of the acceleration coefficient values and inertial forces affecting cargo during transport were verified. For the relevant axes (x – longitudinal and y – transverse), a very strong correlation was found.
